AUTO SIGNAL.

Application -tiled Uctoher 25, 1922. Serial No. $536,914.A

` Besitz @knowmtliat I,`#BENJAM1N BLACK- iionii, afgzitizeir.- of. .the `United States, .and resident of-fAkron, in the-county of Summitandtate of Ohiofhave invented new and Improved Auto Signals, rof'which the following is a full, clear, and exact descri tion.

T is invention relates .to improvements in,automobilesignals an object ofthe in, ,vention beingl toproividearear signal which autotnaticfinl its'-actio1i, and which shpw .total-.driverdnc the rear. the in- `ltentiongiandfoperatiizvnisan ie driver offa :#furthenlobject isjto provide al signal OLthacharacterstated 'in-.which the movement ofthe brake pedal`causes the clos ing of .a `circuit to illuminate a slow sign, and the opcrationof both the brake pedal and the clutch pedal "functions to 'close an electric. circuit and illuminate 'a stop signal.;V i .i zfAifurther object-is to 'provide a si nal mechansm'bf-thecharacter stated in w ich the actionwill. be'positive and in which the structuren-will -zbe simple, durable and efcient. f

. With 4these and other objectsin view, the invention consistsin certain novel features of construction and combinations, and ar- -rangementof parts, as will be' more fully hereinafter described and pointed outl in..

the claims.

Within the box 12, a rotar of non-conduct1ng material. 'This disk 13 supports a pair of electric contacts 14 and 15 respectively to which wires 16. and 17 respectively are connected. y

I have indica in Fi e 1 a simple form of electric circuit w ich will Vanswer the purpose, but it is' to be understood that this invention is hotlinited to any particular circuit. In the. diagram shown, the wire' 45 is grounded; the wire 17 is com nected-to one terminal of the lamp 8 and the other terminal ofthe lamp is connected by a wire 46 witlrthe battery or other source of electricity 47 the other side of the battery beinggrouncled as shown.
